Description

Technical Field

[0001] This utility model belongs to the technical field of material conveying equipment, and relates to an ultra-high temperature material vibration conveying device. Background Technology

[0002] In the metallurgical industry, metallurgical equipment such as blast furnaces and non-ferrous smelting furnaces need to regularly discharge large amounts of high-temperature metallurgical slag. When recovering the high sensible heat of the high-temperature metallurgical slag, an ultra-high temperature material vibrating conveyor is required to transport high-temperature solid particles. Because the temperature of the granular materials is very high, generally exceeding 1100℃, even if the material tray of ordinary vibrating conveyor equipment is made of high-temperature alloy, it cannot work for a long time. The refractory material placed on top of the material tray of the vibrating conveyor is also prone to falling off, and the maintenance cycle is short. Therefore, an ultra-high temperature material vibrating conveyor is needed.

[0003] Currently, there are no mature vibratory conveyor systems in the industry capable of handling materials with temperatures exceeding 1100℃. Existing high-temperature resistant chain conveyors operate at temperatures below 500℃ for extended periods, limiting their potential for modification. Even with existing vibratory conveyor systems using high-temperature alloy for the material tray base plate, the long-term operating temperature remains only around 900℃, failing to meet process requirements. Laying refractory material on the vibratory conveyor tray base plate can guarantee a temperature resistance of 1100℃, but due to the large amplitude of the vibration, the refractory material is prone to detachment. Utility Model Content

[0004] In view of this, the purpose of this utility model is to solve the problem of high-temperature material conveying in the current process of high-temperature metallurgical slag sensible heat recovery and utilization, and to provide an ultra-high temperature material vibration conveying device that can convey materials with a temperature exceeding 1100℃, and has a simple structure, low failure rate, low cost, and can work stably for a long time.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A high-temperature material vibration conveying device includes a vibrating disc and a water cooling system located below the vibrating disc, as well as a control system for controlling the vibrating disc and the water cooling system; the water cooling system cools the bottom of the vibrating disc with cooling water.

[0007] The vibrating disc is arranged horizontally or at an incline. A baffle plate is provided on the vibrating disc along its length. The upper surface of the vibrating disc and the baffle plate have no heat insulation layer and are in direct contact with the high-temperature material. The vibrating disc vibrates vertically or horizontally under the drive of the vibrator, so that the material travels along a preset route.

[0008] A non-contact temperature measuring device is installed above the vibrating feed pan to detect the material temperature and the temperature of the vibrating feed pan; the inlet and outlet pipes of the water cooling system are equipped with measuring instruments to detect temperature, pressure and flow rate. The control system adjusts the vibration frequency and cooling water flow rate in real time according to the temperature. When the flow rate or pressure is lower than the set value or the return water temperature is higher than the set value, the control system will issue an alarm.

[0009] Furthermore, the water cooling system includes a cooling water channel located at the bottom of the vibrating material tray. The cooling water channel is arranged in a serpentine pattern along the length of the vibrating material tray, and the cooling water in the cooling water channel is in direct contact with the bottom of the vibrating material tray.

[0010] Furthermore, when the vibrating feed pan is arranged at an angle, the water cooling system has an inlet at the lower end of the vibrating feed pan and an outlet at the upper end. The inlet and outlet are connected to the cold water inlet and outlet pipes respectively via flexible connecting pipes. The use of flexible hose connections and water cooling technology effectively isolates the vibrating components from the stationary components, while protecting critical components such as the vibrator and bearings, reducing damage to the equipment from high temperatures, and extending its service life.

[0011] Furthermore, the water cooling system includes multiple nozzles spaced apart along the length of the vibrating material tray; the nozzles are located below the vibrating material tray and connected by pipes; the water spray direction of the nozzles is towards the vibrating material tray and completely covers the bottom of the vibrating material tray.

[0012] Furthermore, the vibrating material tray is arranged horizontally, and the water cooling system includes a cooling water tank located below the vibrating material tray, with cooling water connected to the cooling water tank via pipes; the upper part of the cooling water tank has an opening, and the bottom of the vibrating material tray is immersed in the cooling water in the cooling water tank.

[0013] Furthermore, the baffle plate is arranged horizontally or inclined, and is arranged continuously or intermittently on the vibrating feeder.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. The vibrating conveyor provided by this utility model can stably convey materials with a temperature exceeding 1100℃. By setting a baffle plate above the material tray, the material tray can be arranged horizontally or inclined. The material tray can also be designed into a regular or irregular shape structure to ensure that the materials can be conveyed along the preset route, thus expanding the scope of application. The water cooling system effectively reduces the working temperature of the material tray and the baffle plate, allowing ordinary steel to be used instead of expensive high-temperature resistant materials, significantly reducing the equipment manufacturing cost.

[0016] 2. This utility model monitors the material temperature and tray temperature using a non-contact temperature measuring device, and combines this with a control system to adjust the vibration frequency and cooling water flow rate, ensuring stable operation of the equipment within a reasonable temperature range. The water cooling system is equipped with temperature, pressure, and flow rate measuring instruments to monitor the cooling status in real time. An alarm is triggered when the flow rate or pressure falls below the design value or the return water temperature exceeds the design value, ensuring the safety and reliability of the system operation.

[0017] 3. In this utility model, the vibrating feeder and baffle can be designed to be arranged horizontally or inclined according to different process requirements, making it suitable for various material conveying environments and complex paths. In addition to direct contact cooling, spray cooling can also be used to further improve the flexibility and adaptability of feeder temperature control.
